A co-worker at my former job had a terrible sounding S9. Crunchy clipped audio. That radio constantly lost finals. He always took it back to the same clip and snip shop that "tuned" it in the first place.
This sounds all too familiar...local had an S9, still does; and I was told by the tech who tuned it that it was in his shop all the time for finals. He's a local hack and snip shop...
